Class 43/44 locomotives have evolved over time in Romania to class 46.2 made by SOFTRONIC Craiova with modernization of TSAM 2 type equipment. It is the most modern, reliable and efficient modernization made by a rolling stock manufacturer for this series of locomotives from Romania.

If the 43/44 class had a power of 3,400 kW and a V.max of 120km / h, the subsequent modernization variants, including TSAM 2 made by SOFTRONIC, reached 3,840 kW with V.max 120 / 140km / h and 160km / h h, locomotive EC 009 having a constructive V.max of 120km / h.

The CFR Class 47 is a class of electric locomotives built for the Romanian Railways for use on the Romanian electrified network.

They were originally built by Electroputere from 1965 to 1991 and designated as the CFR class 40 or 41.

All Class 47 locomotives were modernized by SOFTRONIC from 2007.

They are operated both by CFR Marfǎ and CFR Cǎlǎtori.

SOFTRONIC suggests four distinct types of modernizations that can be carried out along with repairs on RR, RG and RK type electric locomotives.

Their advantages are as follows:

  • increasing reliability of auxiliary services and systems;

  • cutting down on maintenance times;

  • reduce numbers of contacts and relays;

  • optimizing length of electric wiring used in command and protection.

CSAM 1 upgrades

  • Has the lowest price

  • Needs maintenance of the auxiliary services contactors:

  • Analysis of the contacts state;

  • Cleaning and eventually replacement of the contacts;

  • Needs at the auxiliary services supply high quality contacts that are sorted for each locomotive for an optimal providing

  • It can be perform in any authorized depot or electric locomotive reparation factory

Modernizations and upgrades - comparative study -

CSAM 5 upgrades

  • Auxiliary services need minimum maintenance     (contactors open and close at lull currents)

  • Auxiliary services motors must be repaired according to the maximum maintenance technology (cleaning, changing the bearings, impregnation)

  • Switching elements from the force circuit (selector-graded ensemble, contactors, inverters), they don’t have to have a high rank of usage not to affect the locomotive reliability

  • It can be perform in any authorized depot or electric locomotive reparation factory

TSAM upgrades

  • Even though it is the most expensive upgrade type in time they amortize their costs

  • In the force circuit it is used the static switching without a movement switching element

  • It has high performance for traction

  • Increases life time period and traction motors performances by supplying them with continuous voltage and reduced potential against earthing

  • Represents the recommended solution in case the force circuit components have a high grade of usage, because their repair or replacement have a substantial cost and the reliability remains reduced

  • It can be performed only in the manufacturing company, because it needs complex technological processes ( optical fiber fittings) with extra costs and qualified personal
